and much aborted on the outside cuticle by the mining of parasitic 

 Hymenopteia. 



9. Coccid dark yellow ; 8 lines long, 5 broad, rounded at head 

 and thoracic segments, swelling out on the sides in a line with the 

 middle pair of legs ; fore-legs more prominent than usual ; all the 

 legs small, ferruginous, and projecting oat from the body ; abdo- 

 minal segments covered with fine silky hairs, which are very 

 dense on the last three segments ; anal appendages very short 

 and stout, close together at the base, straight, but slightly open 

 at the apex, the tip of each concave, armed with a fine tooth on 

 loth sides ; on the upper side the abdominal segments clothed 

 with fine white hairs; the last three segments only margined 

 across the lower edge with a row of very small regular acuminate 

 tubercles. 



^. Galls small, reddish, tubular; 2 lines long, with a bell-shaped 

 swelling at the apex. 



Hab. — Thornleigh, near Sydney, on U. piperita (W. W. Frog- 

 gatt) ; Newcastle, on B. sp. (R. Thornton) ; Cambewarra, on B. 

 sp. (W. Bauerlen) ; Lismore, on F. sp. (R. Helms). 



This is a very variable species, but is very constant in having 

 the chamber walls veiy thick at the base, the apex surmounted 

 by a dome-like cup rising above the true ajjical orifice and forming 

 another cavity with a large irregular opening at its apex. They 

 are usually found singly, often on stout stems, but sometimes in 

 clusters, and appear to have a wide range over the coastal districts 

 of New South Wales. 



Some immature specimens obtained lately at Ilornsby give some 

 idea as to how this curious double-celled gall is constructed ; they 

 are generally formed in a stout stem of a young sapling ; the true 

 gall is formed of the woody substance of the stem, while the bai k 

 growing rapidly covers the outer sides and rises above the wooden 

 portion of the gall, a cavity forming on the apex between the 

 bark and the growing gall.

5. Gall cylindrical, rounded at the base, generally widest in the 

 miildle and tapering towards the apex, which is truncate, some-
